Interferometric second‐harmonic generation (SHG) imaging reveals the ubiquitous formation of antiparallel domains in CVD‐grown 2D hexagonal boron nitride. By resolving lattice orientation and SHG phase, hidden domain structures and disorder become visible over large areas. The SHG intensity quantitatively tracks crystalline quality across growth routes,

This article explores how the integration of a thin shell, combined with optimized surface chemistry, enables the design of photodiodes based on short‐wave infrared HgTe nanocrystals. These photodiodes achieve an open‐circuit voltage greater than half the optical bandgap, which drastically reduces dark current. The article also explores the integration

Pixelated Laser with Tailored Emission Spectrum Photopatterned by Digital Holographic Microscopy
Azobenzene‐based surface‐relief gratings inscribed via DHM‐integrated holographic lithography enable programmable pixelated DFB laser architectures. This approach allows independent control of grating parameters across a 2D array, enabling spatially tailored emission spectra.

Modeling a Tunable Narrow Linewidth Laser
In this report a model of a tunable narrow linewidth laser used for telecommunications is presented. The model uses both theoretical analysis and experimental data to create the mathematical models governing its behaviour and is aimed to be useful in a development environment with requirements on accuracy, efficient implementation and adaptability to ...

Dynamic Plasmonic Metasurface Regulated by Drude‐Like Active Spacers
Optical properties of mirror‐coupled plasmonic metasurface are dynamically modulated by controlling intrinsic properties and geometric parameters of Drude‐like active spacers made of transparent conducting oxides and phase‐change materials. The resonance property of a hybrid plasmonic metasurface can be actively regulated by manipulating the ...

Photonuclear Population of 229m,gTh in Th‐Doped Crystals Toward Nuclear Clock Development
This study demonstrates a novel photonuclear approach for producing the nuclear clock isomer 229mTh in thorium‐doped crystals, overcoming current supply limitations. Through cross‐section calculations and Monte Carlo simulations, we identify optimal crystal materials and irradiation conditions, achieving high signal‐to‐noise ratios.
